DNA Replication

DNA Replication

What does it do?

Ahhh DNA. The most important molecule in your body. It holds the genetic code...but what does that mean? What is this "code" we speak of. Well besides making you your unique self with all the different combination of A's, T's, C's and G's...it also makes drum role please....PROTEINS.

Where?

THE NUCLEUS.

Now let's call for backup...

Helicase

Let your DNA relax and unwind with my help.

Polymerase

No nucleotide left behind! I'll make sure all your A's have a brand new T!

Ligase

Yikes the lagging strand is a mess. I'll seal those gaps up.

Now let's talk about those two steps.

How it works...

1. Helicase unzips your DNA... leaving you with two OLD strands.

2. Polymerase zips along the old strands and adds COMPLIMENTARY nucleotides creating two NEW strands.
